Any idea what you would ask the telco to test for? 

I too have seen tdm400ps stop working and output only static noise 
(requiring wcfxs module reload).  The solution to the problem is never 
the same.  Sometimes changing PCI slots, relocating the computer, using 
a noise reducing powerbar, even changing computers completely.  In all 
cases, I'm not 100% confident that the problem has been resolved for good.

If there is a phone-line condition that will trigger the tdm400p driver 
to go into this non-functional state, I'd love to know what it is, and 
how to test for it.

Thanks
Ryan
